DETAILED DESCRIPTION OF THE INVENTION

The following illustrative embodiments and drawings are provided to illustrate the present disclosure, these and other advantages and effects can be clearly understood by persons skilled in the art after reading the disclosure of this specification. As shown in FIG. 1, an integrated handlebar 100 of a bicycle according to a first embodiment of the present disclosure includes a handlebar 10 and two integrated control devices 30.

The handlebar 10 includes a stem 12 on a middle section thereof. The stem 12 is adapted to be installed on a head tube 1 of a bicycle. The handlebar 10 has two free ends 14, which are disposed at two sides of the stem 12 respectively, and adapted to be held by a bicycle rider to control a riding direction.

In the current embodiment, the two integrated control devices 30 are respectively installed on the two free ends of the handlebar 10. Since the two integrated control devices 30 have the same design and are arranged symmetrically, one of the integrated control devices 30 would be explained as an example in the following description.

As shown in FIG. 2 to FIG. 4, the integrated control device 30 includes a base 32, a brake lever 34 and an electronic controller 36.

The base 32 is adapted to be installed on the free end 14 of the handlebar 10. In the current embodiment, the handlebar 10 has a hollow structure, which includes a fixing portion 33, wherein one end of the fixing portion 33 is inserted into the free end 14 of the handlebar 10 and engaged with the handlebar 10. However, it is not limited thereto. In other embodiments, the base 32 could be engaged with the free end 14 of the handlebar 10 with other methods.

The brake lever 34 has a front end 34 a and a rear end 34 b which are opposite to each other. Wherein, the front end 34 a of the brake lever 34 is connected to the base 32 via a pivot, thereby the brake lever 34 can be pivotally controlled corresponding to the base 32. The brake lever 34 is adapted to actuate a brake of the bicycle (not shown), whereby the rider could control the brake lever 34 with his fingers to stop or decelerate the bicycle.

Besides, the brake lever 34 includes a mounting portion 35, which is located at a distance not greater than ¾ length of the brake lever 34 from the rear end 34 b, i.e., it is shown as a range of ¾L in FIG. 2, and is not directly located on the rear end 34 b. Further, in the current embodiment, the mounting portion 35 is a recess 351 disposed at a distance of ½ length of the brake lever 34 from the rear end 34 b, i.e., it is shown as a range of ½L in FIG. 3.

More detail, referring to FIG. 3, the electronic controller 36 of this embodiment is designed based on a rocker switch. The electronic controller 36 includes a base portion 361, a bottom plate 362, a sealing pad 363, a circuit board 364 and an operation member 37. The base portion 361 is disposed in the brake lever 34 toward the mounting portion 35. Wherein, each end of the base portion 361 has a protrusion 36 a, each of which is engaged with a spring 36 b, a button 36 c and an o-ring 36 d. The bottom plate 362 is pivotally connected with the base portion 361 via a pivot 36 e, thereby being able to pivot corresponding to the base portion 361. The bottom plate 362 has two through holes 36 f, each of which is disposed corresponding to each of the two protrusions 36 a. The sealing pad 363 is disposed on one side of the bottom plate 362 which is opposite to the base portion 361, whereby the bottom plate 362 is disposed between the sealing pad 363 and the base portion 361, wherein the sealing pad 363 has two projections 36 g which are fitted in the through holes 36 f relatively. The circuit board 364 is disposed on the operation member 37 and has two contact portions 36 h corresponding to the through holes 36 f, whereby an electronic signal is sent by the circuit board 364 according to a trigger on each of the contact portions 36 h.

The operation member 37 is integrally formed and fixed to the bottom plate 362 so as to make the circuit board 364 be installed between the operation member 37 and the bottom plate. In addition, the operation member 37 has a first operation part 37 a and a second operation part 37 b, wherein after the electronic controller 36 is installed on the brake lever 34, a shape of the operation member 37 is matched with the mounting portion 35, whereby the first operation part 37 a is located on the mounting portion 35 and at about a distance of ½ length of the brake lever 34 from the rear end 34 b, while the second operation part 37 b is located on the mounting portion 35 adjacent to the rear end 34 b of the brake lever 34.

Whereby, with the aforementioned design, the rider could control the first operation part 37 a and the second operation part 37 b with his fingers. As illustrated in FIG. 5, when the rider holds the handlebar 10 with his hand 2 and triggers the first operation part 37 a or the second operation part 37 b with his fingers to control the operation member 37, the bottom plate 362 would be driven by the operation member 37 and moving pivotally corresponding to the base portion 361, and thereby the relative button 36 c on the protrusion 36 a of the base portion 361 would pass through the O-ring 36 d and the through hole 36 f then abuts against the sealing pad 363, so as to make the corresponding contact portion 36 h of the circuit board 364 be triggered by the protrusion portion 36 g of the sealing pad 363. Therefore, the contact portion 36 h of the circuit board 364 sends out an electronic signal to a corresponding electronic component on the bicycle. The aforementioned electronic device includes electronic components, such as an electronic derailleur system, an electronic seat post, a power motor or an electronic suspension system, but it is not limited thereto.

In other words, when the first operation part 37 a is controlled by the rider to trigger the circuit board 364 of the electronic controller 36, the circuit board 364 would output an electronic signal for controlling the electronic component to execute a first action. On the other hand, when the second operation part 37 b is controlled by the rider to trigger the circuit board 364, the circuit board 364 would output an electronic signal for controlling the electronic component to execute a second action, which is different from the first action. More detail, when the electronic component is an electronic derailleur system as an example, the first action and the second action could be an upshifting or a downshifting movement for the electronic derailleur system, respectively. However, when other types of electronic components are adopted, the first action and the second action are not limited to the examples mentioned above.

In this way, by utilizing the design of the integrated handlebar 100 and the integrated control device 30 of the present disclosure, the rider could touch or trigger the electronic controller 36 disposed on the brake lever 34 with his fingers when holding the handlebar 10 or a portion of the handlebar 10 close to the free end. The integrated control device 30 in the present disclosure is not only ergonomically designed, but also can be smoothly controlled by the rider, by which, the rider could respond to the traffic condition quickly. Moreover, the integrated control device 30 is suitable for the rider to use his middle finger and ring finger to control the electronic controller 36 specially.

Furthermore, the first operation part 37 a and the second operation part 37 b of the operation member 37 face toward a lateral side direction of the bicycle, whereby the rider could control the first operation part 37 a or the second operation part 37 b with his fingers conveniently when holding on a terminal end of the handlebar 10 with his hands. Referring to FIG. 2, from a side view of the handlebar 10, the brake lever 34 has an exterior edge 340 which is disposed away from the handlebar 10. In general, when the rider controls the brake lever 34, by pulling the exterior edge 340 of the brake lever 34 with his fingers and drives the brake lever 34 to rotate pivotally corresponding to the base 32 to brake. Hence, the operation member 37 of the electronic controller 36 is preferably disposed between the exterior edge 340 and the fixing portion 33, or between the exterior edge 340 and the handlebar 10, and is spaced apart from the exterior edge 340 with a gap. Whereby, the possibility of mis-triggering the electronic controller 36 by the rider is lower, which then improves the accuracy of controlling.

As shown in FIG. 6 and FIG. 7, an integrated control device 30′ of a second embodiment according to the present disclosure includes a structure similar to that of the integrated control device 30 mentioned above. The description of the identical portions of the structure is omitted here. The integrated control device 30′ is different from the first embodiment in the mounting portion 35′ of the brake lever 34′, the mounting portion 35′ further includes two recesses 352, 353 which are disposed at two opposite sides thereof. Wherein, the first recess 352 is identical with that of the first embodiment and is disposed at a distance of ½ length of the brake lever 34′ from the rear end, i.e., it is shown as a range of ½L in FIG. 7, while the second recess 353 on the opposite side is disposed at a distance of ⅔ length of the brake lever 34′ from the rear end, i.e., it is shown as a range of ⅔L in FIG. 7. The operation member 37′ of the integrated control device 30′ further includes a third operation part 37 e apart from the first operation part 37 c and the second operation part 37 d, wherein the third operation part 37 e is connected to the first operation part 37 c via a bar 37 f, more specifically, the bar 37 f connected with both of the inner surfaces of the third operation part 37 e and the first operation part 37 c. Furthermore, the first operation part 37 c and the second operation part 37 d are both positioned in the first recess 352, while the third operation part 37 e is installed in the second recess 353.

In this way, when the rider triggers the third operation part 37 e with one of his fingers, the third operation part 37 e would drive the first operation part 37 c and the second operation part 37 d to move simultaneously. Thereby the circuit board 364 is being triggered to generate an electric signal correspondingly. In the current embodiment, since the bar 37 f is connected to both of the inner surfaces of the first operation part 37 c and the third operation part 37 e, when the third operation part 37 e is being triggered, the operation member 37′ could be levered to trigger the contact portion 36 h of the circuit board 364 corresponding to the second operation part 37 d, so as to generate an electronic signal.

It shall be noted that the operation member not only could be integrally formed, such as the operation members 37, 37′ mentioned above, the operation member of the present disclosure also could be constituted by a plurality of independent components in other embodiments, whereby the first operation part, the second operation part, and the third operation part could be disposed on different components respectively. Moreover, the electronic controller could be further designed and utilized with a basic structure of a rocker switch circuit, a push button switch or other types of switch circuits, and is not limited to the configuration and the amount of the components as mentioned above.

Whereby, the third operation part is not connected and not operated together with the first operation part or the second operation part. When the third operation part is triggered by the rider, the electronic controller would output an electronic signal for actuating a third action to control the electronic component, wherein the third action could be identical with or different from the first action or the second action so as to perform flexible operation. For instance, when the electronic component is an electronically adjustable seat tube as an example, the first action generated by triggering the first operation part could be lifting the seat tube, the second action generated by triggering the second operation part could be lowering the seat tube, and the third action generated by triggering the third operation part could be locking the height of the seat tube. The above examples are exemplified only, in practice, the operation and the corresponding action may be varied depending on its requirement and are not limited thereto.

Furthermore, as illustrated in FIG. 8, an integrated handlebar of a third embodiment according to the present disclosure includes a handlebar, two integrated control devices 30″ and two auxiliary controllers 50. Wherein, the handlebar includes a main handlebar 15 and two auxiliary handlebars 20. The main handlebar 15 and the integrated control device 30″ are identical with those of the first embodiment, and therefore the related descriptions are omitted here. The integrated handlebar 200 of the third embodiment is different from those of the aforementioned embodiments in that the integrated handlebar 200 further includes two auxiliary handlebars 20 and two auxiliary controllers 50.

To facilitate bicycle riding, the two auxiliary handlebars 20 are disposed on a middle section of the main handlebar 15 and arranged at two lateral sides of the stem respectively. The two auxiliary handlebars 20 extend forwardly with respect to the bicycle, which enables the rider to hold and control a riding direction of the bicycle. The integrated handlebar 100 further includes a bridge 40 adapted to be installed with the two auxiliary handlebars 20. Additionally, on each side of the bridge 40 is disposed with a pad 42, whereby the rider could lean over to rest his arms or elbows on the two pads 42 to have his upper body weight being received thereon and reduce the weight loading on his waist in a long-time riding. Meanwhile, it also enables the rider to lower the height of his upper body, which could reduce the wind resistance in the riding journey, and thereby to save his energy and increase the riding speed.

As illustrated in FIG. 8 and FIG. 9A to 9C, the two auxiliary controllers 50 are respectively installed on the free ends of the two auxiliary handlebars 20. Each of the two auxiliary controllers 50 includes an engaging portion 52, two operation elements 54 a, 54 b and an electronic controller (not shown). The engaging portion 52 and the two operation elements 54 a, 54 b are respectively arranged on two opposite ends of the auxiliary controller 50, wherein the engaging portion 52 is adapted to be engaged with the free end of the auxiliary handlebar 20 to install the auxiliary controller 50 on the auxiliary handlebar 20, and the two operation elements 54 a, 54 b are located on a front end of the auxiliary controller 50 which faces forwardly with respect to the bicycle.

When the two operation elements 54 a, 54 b are triggered by the rider, the electronic controller would be triggered to output an electronic signal to control an electronic component of the bicycle. In the current embodiment, the two operation elements 54 a, 54 b are respectively arranged on two opposite sides of the front end, wherein the operation element 54 a faces toward a top side of the bicycle, while the operation element 54 b faces toward a downside of the bicycle. In this way, when the rider holds the auxiliary handlebar 20, it is convenient for the rider to trigger the operation element 54 a with one of his fingers (e.g. thumb) to trigger an electronic signal for actuating a first action or a second action, or to trigger the operation element 54 b with another one of his fingers (e.g. forefinger or middle finger) to trigger an electronic signal for actuating a second action or a first action. In an alternative embodiment, the installation direction of the auxiliary controller 50 could be adjusted according to the rider's habit to make the operation elements 54 a, 54 b face toward other directions. Meanwhile, the number of the operation elements could be one, three, or more than three, and is not limited to the above embodiments.

In addition, the two integrated control devices 30″ are not limited to be installed on the two main handlebars 15. For instance, in one embodiment, the two integrated control devices 30″ could be installed on the free ends of the two auxiliary handlebars 20, whereby the rider could control the two integrated control devices 30″ conveniently when riding the bicycle with resting his arms or elbows on the two pads 42 and holding the two auxiliary handlebars 20 with his hands, so as to control the brake and the electronic control device of the bicycle. Besides, the above description is not only related to the integrated control device 30″ of this embodiment, but is also applicable to the integrated control devices 30, 30′ of the first embodiment and the second embodiment.

Furthermore, as illustrated in FIG. 10, an integrated handlebar 300 of a fourth embodiment according to the present disclosure is designed based on the configuration of the integrated handlebar 200 of the aforementioned embodiments, wherein it is particular that the integrated handlebar 300 includes four integrated control devices 30″ and is without the auxiliary controller 50 of the aforementioned embodiment. Wherein, two of the four integrated control devices 30″ are installed on the main handlebar 15 respectively, each of which is engaged with one of the two free ends of the main handlebar 15 with a base thereof, while the other two integrated control devices 30″ are installed on the two auxiliary handlebars 20 respectively, each of which is engaged with one of the two free ends of the auxiliary handlebars 20 with a base thereof. By way of the above design, when the rider changes his riding posture, such as changing from holding on the main handlebar 15 to the auxiliary handlebars 20, or changing from holding on the auxiliary handlebars 20 to the main handlebar 15, the rider still can control the brake and the derailleur flexibly and conveniently, which is not only ergonomically designed, but also can be smoothly controlled by the rider.

In other applications, the integrated control device could be installed on a single handlebar, and it not necessary to be installed with at least two integrated control devices. Meanwhile, the locations of each of the operation members are not limited to the embodiments exemplified above, as long as each of the operation members is located at a distance not greater than ¾ length of the brake lever from the rear end, it would match the ergonomics design and provide better control feeling. It must be pointed out that the embodiments described above are only some embodiments of the present disclosure.
